Groupwise 5.5 and Windows 2003 printer help

[wizardPC]

We are in the process of migrating from Netware to Active directory and we have run across a slight problem with Groupwise and Windows 2003--GW doesn't "see" the 2003-based network printers. It sees the same printers if we use NDPS, but they do not show up in the print dialog box. All other programs can see and use these printers, but groupwise cannot.

Any suggestions? We are using 5.5.5
